Blisters oh my!

Today I met the group and decided to walk the 10 miles instead of take a chance on having a long run with back pain. I have never experienced blisters before with running and I have walked but I guess the walking really rubbed my feet the wrong way. Two huge blisters on the bottoms of each foot on the ball of my feet. I couldn't believe it do I really have to deal with this a week before RNR Va Beach! I had to actually pop the blisters because I couldn't walk only on the outside my feet. After popping them it is still painful to walk I am just hoping that they heal for next week or I will definitely be in trouble! Walking next week I guess I need to make sure I have my bodyglide all over.
